Question

an ion m3+ has 10 electrons and 14 nuetrons find the atomic no. and mass no

Answer 1

Atomic number = 13
Mass number = 27

Answer 2

In a Ion
m3+

No. of electrons = 10
No. of neutron = 14
____________________
Now, in a neutral atom ;

No. of neutrons = 14
No. of electrons
= 10+3
= 13

No. of proton = No. of electrons = Atomic no
Atomic no. = 13

Atomic mass
= No. of protons + no. of neutrons
= 13 + 14
= 27
